<div class="markdown_content"><p><em>Originally created by:</em> ph0010421</p> <p>Hello<br/> I'm using the IoDrvModbus v3.5.1.0 library.<br/> I'm using cyclic and triggered channels.</p> <p>I have some questions for people who may have used it before:</p> <ol> <li> <p>When the channel is 'Rising-Edge triggered', is this actually rising edge, OR does it read/write for as long as the trigger bit is high? (level triggered)</p> </li> <li> <p>If I trigger a channel, is there any feedback to tell me that it has 'gone'? I seem to have to hold the trigger bits high for a time (which I don't like)</p> </li> <li> <p>Is there any guidance for how many triggers can go on at the same time (ie if my code wants to trigger two channels at the same time)</p> </li> </ol> <p>Thanks for your help</p> <p>ph0010421</p></div>
